v Patented Oct. 27, I 1931 UNITED sTATEsl PATENT oFFlcE WOLDEMAR HEINITZ, OF CHEMNITZ, GERMANY, AS SIGNOR TO SCHUBERT & SALZEB MASCHINENFAIBRIK; AKTIENGESELLSC'HAFT, OF CHEMNITZ, GERMANY METHOD OF KNITT-ING HOSIERY ON FLAT KNITTING MACHINES .Application filed October 24, 1928, Serial No. 314,805, and in Germany October 2, 1928.

My invention relates to a method of knit- I ting hosiery on flat knitting machines, and to the hosiery obtainedthereby.

According to the new method the work, for instance a. stocking, is started at the welt, narrowed by the old method at the calf andthen widened at either side at the beginning of the heel, but the border loops are only set on alternately, whereupon several rows are knitted plain and thereafter only the lower side of the heel is narrowed, without successive vnarrowing of the instep.

W'ith the new method not only much more suitable goods, such as stockings, are obtained, but the manufacture of such goods is also greatly expedited.

A stocking obtained byrthe new method is 'more suitable than the usual stocking, as it lacks the characteristic narrowing row of loops in the upper portion of the heel which shows distinctly with low shoes. 'Furthermore the stocking does not require any narrowing and therefore is more durable, and by 4the simultaneous widening of the path of the thread guide proper loops are obtained at the edges.v

The manufacture is expedited because rwith the setting on of loops it is not necessary to arrest the machine or to reduce its loops at the edges,

speed as in narrowing, and because after some kplain rows have been knittcd, the narrowing Lof lower portion of the heel without sub-I sequent narrowing at the instep imparts to the heel a more correct shape.

In the drawings aflixed to this specification' and forming part thereof the heel part of a" stocking made according to my invention and 'several stages of ifs manufacture are-illus-l trateddiagrammatically by wayof example.v

In the drawings:

Fi'g, 1 is an elevaton of the spread out heel part of a stocking made in accordance with this invention,

Fig. 2 is a diagram of loops illustrating the l setting on and the alternate formation of they:

Fig; 3 shows the part illustrated in'Fig. 1 sewn to a complete heel. v

Referring to thel drawings, after, the stocking has been finished and narrowed at the leg, the edges from a-a' to b-b' are not covered, as usual but the widening is 'obtained merely by setting on loops, and proper loops are formed along the edges'by the simultaneous widening of the thread-guide path. A

plurality of plain rows are then knitted from b-eb' to 0-0' and the fabric is narrowed' 'a' to o' on a larger scale, showing the formation of the loops 'at the edges.

In the finished heel (Fig. 3) the parts of the fabric illustrated in Fig. l are indicated by corresponding reference letters.

In manufacturing hosiery in accordance with my improved method, the stocking, as stated hereinbefore, is begun in the customary way at the Welt. VVith the beginning of the heel at its upper part, the thread guide path is widened by two needles for every course of loops, while one loop is struck. Following this, a few straight courses are worked, and then the lower part of the heel is narlrowed without a subsequent wedge-like covhasbeen worked to' the series of loops f,\with the thread guided in the direction indicated by the arrow, the thread vguide path in course III is widened. so that the thread is/shifted on the needles of the series g. Before reversing the thread guide path, another loop is struck upon lthe needle of series h, so Ithat in the course IV, two needles are covered by the thread. The thread which at first assumes the position indicated'by the broken lines, is subsequently drawn to the position shown by the full lines, since the loops are not supported by the formation of the loops in the .preceding row. The process is repeated at the opposite side of'course IV, and

so on continually alternating. Therefore,

it will be evident that true marginal loops 25 out subsequent wedge-likel covering.

are formed, which in :the finished product; result a better fitting of the foot and ehminate theflusual widening marks;

Various changes may lbe made in the details disclosed in the foregoing specificatio without. departingv from the invention or sacrificing the advantages thereof. -V In the claims aflixed to this specificationv no selection of any particular 'modfification of the invention is intended to the exclusion of other modifications'thereof and the right to subsequently make claim to any modification not covered by thesev claims is expressly reserved.

I claimz- 1. The herein described method of manu-l wfacturing hosiery inoneI operation upon flat knitting machines, comprising beginning the goods at the Welt, widening the upper part of the heel portion by increasing the successive courses alternatel-y'by two needles for each course While one loop is struck, kntting several straight courses, and then narrowing the lower part of'the heel portion with- 2. As a new article of manufacture, a stocking having loops alternately set om in each :'successive course forming the upper part of I the heel portion whereby to eliminate widen-- ing marks, several courses in the intermediate part of the heel portion beinglkmtted straight,:

'and the courses formng t e lower part of the heel portion being narrowed without. subseliuent wedge-like coverin n testimony whereof I a x my signature.
